Duplicate Messages and Email Delivery

March 29, 2007

Update (8:00 am PST, 3/29): A fix was pushed at midnight (Pacific

Time) that we believe has resolved the problem for messages

submitted after that time. However, it is possible that some users

of some groups may have continued to receive duplicates of messages

that were posted before midnight.

We're aware of the duplicate message bug that began affecting groups

today (Wednesday, March 28th) and are working to resolve the issue

(a side effect of this bug is that some messages are also being

delayed). We have actually pushed two fixes already, but we are

aware that some groups are still experiencing the problem and that

more needs to be done to fully resolve the issue.

There is, however, one silver lining to this bug. It was the result

of our latest system updates intended to improve email delivery

speeds. So once the bugs are resolved, we should see a significant

reduction in the time it takes to deliver messages to

members.

We will update this blog entry as soon as we have more definitive

information on the status of this issue.

Thank you and our apologies for any inconvenience caused by the

duplicate messages.

The Team
